Product Highlights
Vicor’s MI-MegaMod family of single,
dual, and triple output DC-DC converters
provide power system designers with
cost-effective, high-performance, off-the-
shelf solutions to applications that might
otherwise require a custom supply.
Incorporating standard MI-200 or MI-J00
family converters in rugged, chassis mount
packages, MegaMods can be ordered with
single, dual, or triple outputs, having a
combined output power of up to 300W.
Totally isolated outputs eliminate efficiency
penalties and output interaction problems.
